REAL Housewives of Beverly Hills star Brandi Glanville has hit back at Denise Richards, calling on the actress and reality star to “take responsibility” for her actions.

The pair’s good friendship has turned sour after Brandi alleged she and Denise had been engaged in a months-long affair.

Denise has always denied Brandi’s allegations, and in a tweet on Tuesday, Brandi slammed the actress, writing: “Maybe if you’re so worried about hurting your children then as a married woman you should not f**k your cast mates and expect it not to get out take responsibility for your part DR.”

The tweets come after a teaser clip for next week’s episode saw Denise confront Teddi Mellencamp, 39, after she revealed to the group the affair accusations.

“I don’t know Brandi Glanville very well. I don’t know you well, either,” the daughter of music icon John Mellencamp said at dinner with the women.

Denise then revealed: “I will tell you, Brandi said that she’s had sex with some of the people from this group.”

Kyle Richards, 51, looked stunned and asked: “Someone at this table right now?” before Denise confirmed, ”yes.”

The emotional confrontation comes after the Housewives headed to Rome for their annual girl’s trip.

A fun shopping day quickly turned into screaming and tears as Denise was confronted by Brandi’s shocking hookup claims in last week’s episode.

Teddi was the first to break the ice on the topic as the cast were having dinner at their hotel restaurant.

The new mom told the actress that Brandi: “told us a lot of things you said about me and other people at this table.”

“I didn’t say anything about anyone to Brandi at all. I’ve hardly talked to her. I have not spent much time with her, I don’t talk to her much,” Denise defended.

After a few more minutes of back-and-forth, Teddi blurted out: “Denise, I’m not going to torture you any longer. She said you two had sex.”

The mom of three looked stunned and began laughing as she denied the allegation.

Denise continued repeating “that is not true. It is not true at all,” as she insisted she began to get emotional and tearfully begged Bravo not to air the scene.

“Are you f**king kidding me? You guys… I’m going through so much stuff, it has nothing to do with any of us, it has nothing to do with this show.

“And Bravo, Bravo, Bravo,” the reality star said – referencing the line Housewives claim is used when they do not want a particular scene to air.

“I’m a very married woman and I love my husband to death,” Denise insisted.

She pleaded to the cameras once again: “Please do not air this, please. That is not true.”
